Well, in such a fanfic, perhaps Archer sacrifices his arm while saving Arturia from a great danger. Maybe it could be a powerful enemy attack and Archer jumps in the way, taking the brunt of it on his arm to protect Arturia. This would be a very heroic and selfless act on Archer's part.
The concept of time and fate is important. Since they exist in different timelines and yet are brought together in this fanfic, it can add a layer of mystery and destiny to their relationship. For example, Archer Shirou might be trying to change certain aspects of his past related to Arturia. Their relationship could also be influenced by the power of the Holy Grail. Maybe it has some lingering effect on them that either draws them together or creates obstacles. Additionally, the exploration of their unspoken feelings, especially Archer Shirou's repressed emotions towards Arturia, can be a major element in the fanfic.
Well, a 'archer losses arm fanfic' might be centered on the consequences of the archer losing their arm. Maybe it's a tragic event that sets off a chain of events in the story. It could explore themes like the archer's struggle to adapt, their journey to regain some form of their former self, or it could even be a part of a larger plot involving other characters who are affected by this loss in different ways.
Well, in Archer fanfic involving Artoria and Shirou, their relationship can be quite different from the original story. Sometimes, Shirou might be more influenced by Archer's combat style when dealing with Artoria. Artoria, on the other hand, could see elements of the future (as Archer is from a future timeline) in Shirou. This can lead to new storylines and character growth. It can also make for some very engaging reading as the fanfic writers play with the existing character dynamics and add their own twists.
In Archer - themed fanfic, Artoria and Shirou can play various roles. Artoria might be a key figure in a quest that Archer and Shirou are involved in. Her knowledge and power could be crucial for the success of the mission. Shirou, influenced by Archer, could have a different approach to working with Artoria compared to the original story. For example, he might be more cautious or more aggressive depending on what he has learned from Archer.
It could be that Archer's loss of an arm makes him more determined. He might start to train harder with his remaining abilities, and in the process, discover new skills. This could also make him more respected among his comrades. Arturia, on the other hand, might start to see Archer in a new light, not just as a fellow fighter but as someone she deeply cares about on an emotional level.
In the visual novel, the battle between Shirou and Archer is intense. Shirou, with his unwavering beliefs, often uses his projection magic in unique ways. Archer, on the other hand, has more combat experience and a wider range of skills. Their battle is not just about physical strength but also a clash of ideals. For example, Shirou's ideal of being a hero who saves everyone conflicts with Archer's more cynical view of heroism, which is developed from his own past experiences. This ideological difference adds depth to their confrontations.
In many fanfictions, Shirou's relationship with Archer is complex. At first, Archer may be cold towards Shirou due to his own past and the knowledge of what Shirou might become. However, as they interact more, they find common ground in their fight against enemies. They start to communicate better, and Shirou might even look up to Archer as a mentor figure, which gradually builds a more positive and collaborative relationship between them.
It's a very interesting plot point. Once Rin finds out, she might start to analyze all their previous interactions. She'll likely remember how Archer sometimes showed hints of Shirou's personality. It could also make her wonder about the future of their relationship, whether they can still work together as they did before.
I'm not sure of the exact name, but there could be a fanfic where the setting is a dark, alternate universe. Archer and Artoria are on different sides initially. When they finally meet in combat, Archer loses an arm. This event changes the course of the story as they both start to question their allegiances and the reasons for their fight. It has some really interesting character development for both of them.
